The Enterprise Service Bus (ESB) is an important systems integration technology often closely associated with Service Oriented Architecture (SOA). Some maintain that an ESB should not be used apart from SOA. Others see the ESB simply as the next generation of middleware, incorporating the best of its predecessors, Enterprise Application Integration (EAI) and Message Oriented Middleware (MOM), and a candidate for any integration requirement. Is the ESB a one-size-fits-all solution to be trusted for any integration requirement, or must its use be carefully considered with proper due diligence based on application complexity and/or the presence or absence of a defined SOA? This thesis probes these questions in an analysis of a world-wide survey of 230 industry SOA and middleware professionals conducted via the LinkedIn Professional Network during a six week period in November and December of 2010. In addition, the thesis applies a review of the survey results and current SOA and ESB literature to an architectural decision being made within the Systems Engineering and Application Development (SEAD) Practicum in the Master of Science program in Computer Information Systems at Regis University in Denver, which provides support for the University's Academic Research Network (ARN). An ESB has been proposed as a new architectural component for the ARN infrastructure and this paper reviews the merit of this proposal. This thesis employs an interpretivist epistemology, understanding that there may be more than one acceptable answer to the question, "When is an Enterprise Service Bus an appropriate component of an integrated technology solution?"
